Osteoporosis
Study 1
Osteoporosis due to inactivity**
Authors, title of the study and source:
Eyres KS, Saleh M, Kanis JA. Effect of pulsed electromagnetic fields on bone formation and bone loss during limb lengthening. Bone 1996, 18: 505-509
Number of patients: 13
Disease:
Operative leg lengthening (by 9 – 19 year old patients)
Treatment:
15 Hz, rectangular, 4pcs/day, as long as the distraction lasted (< 12 months)
Improvement (DXA measurement) bone loss due to immobilization could be reduced by MFT: Above the surgical position a significant increase in bone density in the MFT group was measured after 3 months, which lasted until the end of the study (12 months). Below the surgical position, bone density decreased in both groups, but significantly less in the MFT: after 2 months: MFT 10% loss of bone density, control 33% after 3 months: MFT 13% loss of bone density, control 54%
Remarks:
It is believed that the MFT settings can be better selected so that the possibilities of therapy can be eminent.
Study 2
Osteoporosis (Postmenopausal)*

Tabrah F, Hoffmeier M, Gilbert F, Batkin S, Basset CAL. Bone densitiy changes in osteoporosis-prone women exposed to pulsed electromagnetic field (PEMFs). J Bone and Mineral Research 1990; 5(5), 437-442
Number of patients: 20
Disease:
Postmenopausale Osteoporosis
Treatment:
10 pcs/day (overnight), 12 weeks, 72 Hz, 28,5 G. One Arm was treated with MFT, the other wasn’t.
Improvement:
Bone density measured on the forearm, increased significantly. Within 12 months after completion of therapy, this effect decreased again.
Remarks:
The authors think that this therapy is really suitable as a full- body therapy for clinical use for prevention and treatment of osteoporosis. They believe that the treatment should be continued, rather than, as here, stopped after 12 weeks.
Study 3
Osteoporosis (Postmenopausal)*
Authors, title of the study and source:
Tabrah FL, Ross P. Hoffmeier M, Gilbert F. Clinical Report on Long-term Bone density after short-term EMF Application. Bioelectromagnetics 1998, 19: 75-78
Number of patients: 20
Disease:
Postmenopausale Osteoporosis
Treatment:
10 pcs/day, 12 weeks, 72 Hz, 28,5 G. One Arm was treated with MFT, the other wasn’t.
Improvement:
Bone density measured on the forearm, increased significantly. Within 3 months after the therapy, this effect decreased again and after 8 years there was no difference between the treated and the untreated area.
Remarks:
The authors think, that this therapy is in combination with other therapeutic approaches appropriate
Study 4
Osteoporosis (Postmenopausal) *
Authors, title of the study and source:
Bilotta TW, Zati A, Mignani A, Mari G, Davoli O, Zucchini E. Pulsed electromagnetic field therapy for postmenopausal osteoporosis. 1993, Electricity and Magnetism in Biology and Medicine; San Fransisco press, San Fransisco CA; 761-763
Number of patients: 100
Disease:
Postmenopausale Osteoporosis
Treatment:
Sinus, monodirectional, 50 G, 50 – 100 Hz, 30min/day, daily, 4x20 days within 2 years (that means 20 days per half a year). SPA measurement radius. MFT was compared with control and with nasal calcitonin 110 E.
Improvement:
The untreated control group showed a 3% bone loss after 2 years. Only MFT: 1,44 % bone loss, only calcitonin 0,42 % bone growth; MFT plus calcitonin: 2,3 % bone growth.
Remarks:
The combination of MFT with hormones seems to be the best treatment method.
** The treatment with pulsating magnetic field seems to be superior because of double blind controlled randomized studies of the Placebo-treatment.
* The treatment with pulsating magnetic field seems to be superior because of the controlled studies of the control-treatment.
